I think the reason why Dr. Seri invited the BBC journalist to conduct an interview on the stage because he just wanted to emphasize what this corrupt government has done for years and let the world directly perceive what the protesters is currently aiming and doing. At this moment, some journalists do not report what exactly happens; therefore, the misconception may occur among the foreigners. He just wanted to make it clear.
I believe most Thais always accept the unanimous vote from any general election if it is based on the fair and lawful system. It is undeniable that this regime is currently controlled by someone outside the politics. Should we still put our trust in democracy?
